# Module type Iobuf_intf.Bound

    module type Bound = sig .. end

An iobuf window bound, either upper or lower. You can't see its int value, but you can save and restore it.

    type ('d, 'w) iobuf

    type t = private int

    val window : ('a, 'b) iobuf -> t

    val limit : ('a, 'b) iobuf -> t

    val restore : t -> ('a, Iobuf_intf.seek) iobuf -> unit

    val sexp_of_t : t -> Sexplib.Sexp.t
